The bug was in field mapping when saving AI-generated templates:
- Changed 'type' to 'template_type' (correct column name)
- Changed 'body_template' to 'body_html' (correct column name)
This fixes the 400 Bad Request validation error:
'notNull Violation: MailTemplate.template_type cannot be null'
Now AI template generation works correctly.

- Google provides App Password with spaces (e.g. 'abcd efgh ijkl mnop')
- Backend now automatically removes all spaces before saving
- Users can paste password directly from Google without manual cleanup
- Also trim gmail_user for safety
- Changed gmail_password to gmail_app_password in request body destructuring
- Matches frontend Settings.jsx which sends gmail_app_password
- Backend still stores as 'gmail_password' key in database (for backward compatibility)
- Added full CRUD endpoints for mail templates (create, update, delete, preview)
- Introduced Joi validators for template create/update/preview
- Updated routes/controller to support ID and type lookups
- Built React Templates page with HTML editor, preview, and clipboard helpers
- Added navigation entry and route for /templates
- Enhanced documentation (README, QUICKSTART, KULLANIM, frontend/backend README)
